To the latest on the mysterious shooting of a prominent New York real estate tycoon and political power broker at his castle, one of the biggest private homes in the U.S. Gary Melius says he has no idea who would want to harm him. ABC's gio Benitez has that story for us. Reporter: This morning, with his would-be assassin on the loose, the owner of one of America's largest and most exclusive properties, New York's oheka castle, is afraid for his life. Insisting he does not know who shot him. With around the clock police protection, 69-year-old Gary Melius tells us from his hospital bed, I look forward to coming home. I look forward to getting back to work. Oheka castle is the kind of place most only see on TV. With gardens fit for kings. But Monday afternoon with Melius sitting in his car a gunman wearing a black mask fired up to three shots, one bullet hit him in the head but never penetrated his skull. He went into shock. Melius who spent $30 million restoring the iconic castle is so politically connected, top elected officials were at the hospital distraught. It's terrible. Terrible. Reporter: Just months ago Melius, a political donor was at the center of an enormous scandal accused of using his access and connections to get the Nassau county police to arrest someone. The police commissioner resigned soon after. Both he and Melius denied wrongdoing. But who would want Melius dead? Police don't have a motive or suspect. But according to "The wall Street journal," surveillance video showed two men waiting in a vehicle for two hours before the attack. When Melius sat in his car, the masked gunmen started shooting into the driver's side window. Melius also telling us "If this near-death experience has done anything, it is a reminder to live each day, celebrate life and embrace your family." And back here at the castle police are launching day three of that manhunt but they say Melius is still having a really hard time remembering the details of that shooting, robin. Good to see he is recovering. All right, gio, thank you very much.
